  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281. 🇬🇧
  • ❗ Youhaiella is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: CGMCC: 2; LMG: 1; JCM: 1.
